Owner Arlen Hill is an extraordinary young plant hunter and propagator. You can visit his private botanical garden 90 minutes north of Seattle, and buy plants on site (plan half a day, but he is not open daily), or mail order them. He brings van-loads of stock to local specialty sales like at Heronswood and the Rhododendron Species Garden sale.
He specializes in hardy orchids and woodland perennials, and has LOTS of exotic plants. He has more species of Sorbus than the Arboretum in Seattle. No matter how much a plant geek you are, he will have plants you never saw before.

I have ordered from ARE several times, and am impressed by their wide selection of roses, their friendly and knowledgeable staff, and their large, healthy plants.

Almost Eden has a fine selection of plants, and are an especially good find for Southeastern gardeners. Healthy and often unusual plants, an informative web site, very fine customer service and well packaged plants.

And if anything isn't right, they will try very hard to fix things.

Morganville Flower Farm is the perfect antidote to "same old - same old". While not the biggest local flower center around, they have the best selection of not only the new, but also of the very best plants available. Many of the cultivars I have found there are simply not available anywhere else locally.
Harry, the owner is a very special guy. He closes shop by mid-July to visit almost all of the flower shows and trial gardens to scout out his selections for the following year. He is really into his plants and the customers are the beneficiaries.

There is no mail order but if in the area be sure to drop by.

This company sells seeds of vegetables, herbs and flowers in either sampler or regular packs. The sampler seed packs are very inexpensive (40 cents in 2018) with a smallish amount of seeds. I find it perfect for a household of two. They also sell some plants. Shipping was reasonable, although I've never ordered plants from them. (Vermont to Washington is a bit of a stretch...)

I recently learned about Kitazawa Seed Co here on the NGA. I ordered seeds of a variety of veggies, and they arrived in my mailbox 2 days later! They also included their catalog which is a very interesting read. I love that they also include recipes for many of the seeds they sell. They've been at this for 101 years, so you know they are a great company! I'll definitely be a return customer.

Has a good selection of Texas native plants as well as plants adapted to hot, dry climates. There's also a good selection of herbs, annuals, and perennials. There's also lots of succulents and neat yard art.

Received my first order from Shady Rest Gardens and was very impressed with the size and quantity of the fans. And the bonus was large and one I would have picked myself. Communication was also prompt and informative.

Altogether, an overall good experience.

Great varieties, informative website, quick shipping and excellent product. Would not hesitate to recommend TGS to fellow gardeners!

Their order processing time was a bit slower than other seed companies but they warn you ahead of time that it is a small business with few employees.

The seeds, on the other hand, are awesome! I ordered a bunch of tomato plants, some basil, peppers and squash. Everything germinated and the plants are doing well! I would not hesitate recommending them to fellow gardeners!

Excellent company with a wide selection of plants. Easy to navigate web site. Extraordinary packing, timely, helpful (great customer service)!
